I'm working on assembling a LabVIEW setup that has the ability to measure Pressure, Temperature, RPM, Voltage and Amperage. I believe I have identified the correct modules but am looking for another opinion before giving anyone a lot of money.
Requirements:
- Temperature: Able to measure 7 channels of temperatures ranging from ambient to 300 degrees F.
- RPM: Able to measure shaft RPM up to 3600.
- Voltage: Able to measure up to 500 Volts, 3 phase AC.
- Amperage: Able to measure up to 400 Amps, 3 phase AC.
- Pressure: Able to measure 2 channels of various ranges of PSI
(specific transducers to be identified at a later date).
The Gear:
- Chassis: cDAQ-9174 with the PS-14.
- Temperature: T type thermocouples and NI-9212.
- RPM: Monarch Instrument Remote Optical Laser Sensor and NI-9421. Laser uses 24 volts but returns 19 volts when target is present and 0 volts when the target is not present.
- Voltage*: ATO three phase AC voltage sensor ATO-VOS-3AC500 outputting 0-5 volts and either NI-9224 or NI-9252.
- Amperage*: 3, Fluke i400 units returning 1mV per Amp and either NI-9224 or NI-9252.
- Pressure: 2, 4-20mA 2 or 3 wire pressure transducers to be identified at a later date, and either NI-9203 or NI-9253.
*Voltage and amperage will be measured on the same unit
Questions:
- RPM: Will the NI-9421 record a pulse of 19 volts?
- Voltage and Amperage: What is difference between the NI-9224 and the NI-9252, which one would work best for my application?
- Pressure: What is the difference between the NI-9203 and the NI-9253 other than input resolution and which one would work best for my application? Resolution is not a priority.
- Overall: Anything stand out as a red flag?
I have not tried any of this equipment out myself.
Thanks in advance for your expertise and patience.
